After getting naked with stars like Conan O'Brien and Sandra Bullock, Chelsea Handler took her last shower on "Chelsea Lately" on Tuesday night for the final episode ... and it may be the funniest video yet!

The series finale of the comedian's E! talk show aired tonight, with a surprise appearance from Ellen DeGeneres herself.

Jennifer Aniston, Sandra Bullock and Mary McCormack took part in a group intervention -- with Sandy bringing out Handler's ex-boyfriend 50 Cent for another surprise reunion.

"My security guard caught you douching with Listerine. There’s a reason that your stage is so far from the audience," Aniston said while addressing Chelsea's hygiene.

"We love you Chelsea, but you gotta get our head out of your ass, your vagina, I don’t know where you have it set," added Bullock. "You're not funny. You're not cool. I think you're probably one of the most unhip people I've ever met."
